The invention relates to improyents in heaters adapted to be used for 1 .11. pur-- w such as whippingcream and eggs, d T for its ob ect the provision of a 5 new and improv beater of the above character which is sim lo and inensive in construction, and which is eficient in operation.

Another object is to provide a new and proved liquid heater or. whip which is 19 adapted to apply an. =1 ve and efiectual r 12; force on the liquid, thereby so 1' mg to divide the li uid into very ute p foles and to cause a arge ount of fo r: and mill in M; =1

These vanes in the rand refer g. d is to seal view on in the plane nimh ons and alternahve come a heater head consisting of a stationary bot- I tom plate in the form of afdisk or d1sh 14 and a rotatable fan or propeller member 15. The dish 14 is provided with a central base plu 16 which is adapted to rest on the bottom of the container (not shown) for the material to be whipped, and the shank of whi is threaded onto the lower end. of the r The dish 14 is also formed with a plurali of openings of any suitable sha e-throug which the material to be Whipped is adapted to be forced by the fan member 15. In present instance these openingsare a plurality of closely spaced and long radial slots ll.

The fan or propeller member 15 is what-- ably mounted on t e shank of the plug 16 directly over and next to the dish 1%, and is provided with a plurality of inclined blades,

instance are formed by a plurality o v nornately long rind short radial slots 19 d 20 cut in from the periphery of the fan Hmher 15.

l have found that the best results are-obtained when the slots l7, l9 and 20 are non row and ore iorrnedwith shor ed es m? or gether, thereby resulting in increased s earing power.

'Extend I up from one side of the dish ll y formed integral therewith is a .a; ll plate 21 which when the ter is in. use is positioned in the path of the liquid swirling about the tar d around th the fan umber l5. The to direct'the sr liquid into the nor ten to pass it throng the I hend,d also shaped to so direct the liquid that its fall it will imprison and car along all articlw oi nir thereby ltlng in a large reg of for y suitable on may M provid ior driving the fan member 15. In the r instance, a large 22 is journalod' on a stul secured to the baclr of the bracket l2, on is Prefers. ly the stud 23 is riveted to the bracket 12, and the hdle 24 is formed integral with a lurnlity of sees 25 rivctedto the "i r gesr 22 hes a plurality of holes or slots 26 stped therethrough next to its m h...

so plate 21 is shaped rovided with u suitable handle 24;. 1

' outer ends of the pinion. 27 is rigidly connectedto the fan member 15 by means of two parallel rods 28 extendin along opposite sides of the rod 10 and a apted to-be revolved about the latter.

The metal at the periphery of the gear 22 is bent at the slots 26 into the form of a flange 29 extending away from the bracket 12. The slots 26 thus extend into a plane. be 0nd the pinion 27, and ermit the latter to e moved axially intoan out of en gagement with the gear 22, thereby facilitatthe assembly and dis-assembly of the beater.

It will be seen that'I have provided a simple and inexpensive beater which is eflicient in operation and which will beat material such as cream and eggs ina very short time. The beater has unusual shearing powers-and causes a lar e amount of foaming. All of 1 member having a plurality 'of'slots, a pro the materia being whipped or beaten is worked on uniformly, thereby resulting in a homogeneous and improved product.

I claim as my invention:
